Effective practices in probation supervision; A systematic literature review

In recent decades, the violent radicalisation of juveniles and young adults has become a pressing concern for policymakers, researchers, practitioners, and communities worldwide. While considerable attention has been devoted to psychological vulnerabilities, socio-economic marginalisation, and community-level influences, the broader context in which violent radicalisation develops is often overlooked. At the same time, the increasing involvement of young people in violent extremist offences highlights the urgent need for effective prevention efforts. Addressing youth radicalisation has become a complex and evolving challenge for families, educators, mental health professionals, law enforcement agencies, probation services, and security authorities.

At CEP, we are fascinated by research from across Europe and beyond, and by helping it reach the people who can use it. Ruth Armstrong, CEP Research and Policy Officer, went to the 26th Annual Conference of the European Society of Criminology (EuroCrim 2026 – Working Group on Community Sanctions and Measures) that took place in Warsaw, Poland, from 9–12 September 2026.

Against a backdrop of overcrowded prisons and net-widening (with ever more people drawn into supervision), three questions kept coming up in the research: how time shapes justice, what we mean by success, and how we define harm.

📢 Have you registered yet? CEP’s final workshop of 2026 takes place on 24 November in Barcelona, bringing together professionals to explore how technology is being used across probation services in Europe.

The Workshop on Alternatives to Detention and Technologies: Deep Diving into New Trends will look beyond artificial intelligence to examine the different ways technology is shaping probation practice, from staff training to working with clients and collaborating with other criminal justice partners.

The CEP Leadership Excellence Training, held on 20–21 October in Zagreb, Croatia, brought together Directors General and senior probation managers from 11 European countries for a two-day interactive programme focused on leadership, communication, staff development, and international cooperation.

On behalf of Ms. Jana Špero Kamenjarin, CEP Secretary General, it is my pleasure to invite you to submit a proposal to conduct an evaluation within the CEP work programme.
